Hi Helmut,
hope you are doing fine and my post here fits to the subject.

I`m wondering how to show a power achieved after completion of the first stage in parallel design using Power2Stage functions, according to Potvin C algo?

When I do it for crossover study using interim.tsd.in function I can extract the value of Power Stage 1 component, but how about parallel study?
